| Aim | to assess whether systematic reviews published up to 11 November 2012 in periodontology and implant dentistry report and discuss the influence of funding sources on study results. |
| Level of Investigation | Descriptive |
| Summary of Findings | Of 146 systematic reviews included in the assessment, only 45 (31%) reported the funding sources of primary studies. Fourteen (10%) systematic reviews discussed the potential influence of funding sources on study results, that is, sponsorship bias. Thirty (21%) systematic reviews attempted to investigate publication bias, 98 (67%) systematic reviews contained no description of such assessment, and 18 (12%) systematic reviews reported that the investigation of publication bias was not possible due to the small number of primary studies included. |
